TO'ALL WHOM IT MAY CONCERN: v

I Be it known that I, GHAnLns C. SAVERY, of the city of Philadelphia, in' the county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Water-Coolers and Refrigerators; and I dohereby declare that the following is a full and exact description thereof, referencebeing to the accompanying drawings making a part of this specification, in which- Figure 1 is a side sectional elevation of my cooler and refrigerator. Figure 2, a plan sectional view of the same. 1 Figure 3, a sectional view ofthe device by means of which I secure the spout to the metal of the water- The nature, of my invention consists in a peculiar mode of constructing water-coolers and refrigerators, in whichare combined 'cheapness and strength, as will be hereinafter shown. A

. To enable o thers skilled in the art to make and use my invention, I will',new proceed and describe its construction and operation A A -is the wooden box or casing of my cooler.

N N is a nomconductor substance between the casing A A and the metallic sides, top', and bottom of the cooler. i l

G C C P, figs. I, 2, is the icc-and-water tank, and 0 PC 0' the air-chamber. I I St is a perforated shelf in air-chamber. As many as may be desired may be .placed there in any suitable position.

S is the spout for the water-tank. It can he set on any face of the water-tank.

D isthe door of air-chamber. It can also he placed either at the end or on any of the sides of the air-. chamber, I c I h It h are holes, covered inside witha gauge, metallic or otherwise, to allow the vitiatcd air to pass out, and also keep insects out. I Y

L is the top lid of the water-tank.

IBoth door -D and lid Lave made of wood and metal combined, and packed inside with the non-conductor substance N. l v

The above,constru'ction shows the gener'alshape of construction my cooler is to have, viz, the space divided in but two compartments, one-air-chamber in contact with one ice-and-water tank.

When my cooler is to be made of sheet metal entirely, the simplest mode of construction seems to he bending one sheet, of proper size, so as to form the sides of both the ice-and-water tank and the air.-

chamber of one single-sheet of metal, one end, or one side, being left open to receive door D, and dividing the space into the two said compartments by means of a. partition, P, soldered or riveted, or both, as shown in fig. 2. j c I But if I prefer making my cooler of cast metal, or cast and sheet metal combined, the simplest method is to" build both compartments separately, and then tojoin them together by means of flanges and rivets, or solder, or both, in any of the knownand usual ways,

I would here remark, that if this'last modeof construction is preferred, the cooler still has the desired form, vi z, but two compartments, one ice-and-water tank, and one"air-chitmber, the one side of the icetank forming the hacker one side of the air-chamber, no more riveting or soldering being needed in one than the other case.

I also will enamel my cooler in .the following way: I I t When my apparatus is, as aforesaid, made entirely of sheet metal, I will apply to all its parts, viz, the

inside or the outside, or the inside and the outside ofall its metallic face, a coat of enamel of any color; but.

when I construct my cooler of cast metal, or cast and sheet metal combined, viz, when the two compartments are made separate, they should also be enamelledseparately, and ,then jointed together, as afore described, or in any other suitable way. 1

This mode of enamelling my water-cooler throughout nll'its parts oflers many important advantages: First, it prevents the metal from rusting.

Second, it covers and closes all the pores of' the metal. Third, enamel being, like glazes, a. bed conductor, diminishes much the conductibleness of the metal of the cooler or'refrigerator, thereby retarding the melting of the ice, end in a. measure preventing the entrance of heated orhot air in the air-chamber.

- Therefore, having described my invention, what I claim as such, and desire to secure by Letters Patent of the United States, isv The combination and arrangement of the enamelled ice-and-wnter tank 0 C C B and its lid, L, with the enamell ed air-chamber G C and its door 1), constructed substantially as herein specified.
